Packard Bell has unveiled two all-in-one PCs and a touch-screen monitor, all designed to make use of the multi-touch user interface support in Microsoft's upcoming Windows 7 operating system.

Due in October for the official release of Windows 7, the OneTwo Series PCs and Viseo 200T Touch Edition monitor are designed to provide a fast and intuitive interface using multi-touch technology support, according to the company, which is now part of Acer.

The OneTwo M is integrated inside the case of a 20in LCD monitor supporting a screen resolution of 1,600 x 900, and is priced from £599. The larger OneTwo L is a 23in model supporting the full high-definition video resolution of 1,920 x 1,080 at a cost of £899.

Both models have integrated or discrete graphics, up to six USB ports, a 5-in-1 Flash card reader and an integrated webcam, and will be available from 22 October.

Packard Bell said that the OneTwo L is based on an Intel Core 2 Quad processor and offers an optional Blu-ray drive, 5.1-channel surround sound and a TV tuner supporting analogue and digital broadcasts.

The Viseo 200T, meanwhile, is a standalone 20in display that can add multi-touch support to any PC with Windows 7. The technology allows users to rotate images, flip pages, zoom in and out, and draw on the multi-touch screen with simple hand gestures.

The monitor features built-in stereo speakers, 16:9 display ratio, 50,000:1 contrast ratio, and VGA and DVI inputs. It will be available from mid-October for £199.
